The first phase of Gov. Andrew Cuomo’s $8 billion overhaul of LaGuardia Aiport opened to the public this weekend, which includes a new concourse and 11 gates at Terminal B. Construction company Skanska on Wednesday released additional information about the project, detailing everything from its planned 1.3 million square footage to its use of 40,000 tons of steel. In total, the redevelopment of LGA’s Terminal B will cost $5.1 billion and bring 35 new gates and two new concourses.

“While leaders in Washington only talk about investing in infrastructure, in New York we are actually getting it done, and now travelers from across the world will start to see and experience a whole new LaGuardia,” Cuomo said in a statement.

Upon completion, Terminal B will measure over 1.3 million square feet, including the newly opened Eastern Concourse, which measures 250,000 square feet and has 18 gates. The terminal’s parking garage opened in February and includes 3,100 parking spots, all equipped with a system to provide a real-time view of available spaces.

Two pedestrian bridges will be constructed across active plane taxi lanes, connecting the main departures and arrivals hall that will open in 2020 with the two island concourses. According to the company, the bridges will offer travelers views of the Manhattan skyline as they head to and from their gates.

The new concourse will also feature 50 vendors, including a food hall with local mini-chains (including Shake Shack and Irving Farm coffee), retail space, and an indoor park.

Terminal B, serving Air Canada, American Airlines, Southwest and United, and Terminal C, serving Delta, will be able to hold 30 million passengers per year after the redevelopment wraps up.

On the materials and labor end of things, Skanksa said the project includes 40,000 tons of steel. And 10,000 individual steel pieces, measuring 12,000 tons, will weigh more than the Eiffel Tower.

In an effort to stay green, Skanska recycled 21,604 tons of concrete from the demolition of the original structure with about five million pounds reused at the job site.

Under construction, Delta’s Terminal C has an expected opening in 2021. And an environmental review is underway for the proposed AirTrain, which would provide a reliable trip to LaGuardia from Midtown Manhattan in 30minutes.
